Abstract: L- (+)-Lactic acid production from corncob hydrolysate as a cheap carbohydrate source by fed-batch fermentation of Rhizopus oryzae HZS6 was studied.After 96 h of fermentation in a 5 L fermentor, the final concentration of ammonium L-(+)-lactate, average productivity(based on initial xylose concentration) and max(+)-lactate was 98.8%.

Key words: Corncob hydrolysate, Ammonium lactate, Rhizopus oryzae, Fed-batch fermentation
